Definitions

  • This invention relates to a plurality of floor panels and to floor panels which are used hereby.
  • the invention relates to floor panels that can be installed according to the fold-down installation method.
  • Several embodiments for the coupling parts that allow coupling by means of a downward movement on one floor panel with respect of another floor panel in a fold-down installation method are described in WO2017/115202A1 .
  • first floor panels consisting of a first series of floor panels, herein below named first floor panels, and a second series of floor panels, herein below named second floor panels, wherein the first floor panels show the following characteristics:
  • first floor panels and second floor panels are compatible, by which is meant that they, anyhow at least at certain edges thereof, can be coupled to each other.
  • the floor panels characterized in that the coupling means, more particularly coupling parts, of the first pair of edges of the first floor panels and the coupling means, more particularly coupling parts, of the first pair of edges of the second floor panels are compatible with each other, as well as the coupling means, more particularly coupling parts, of the second pair of edges of the first floor panels and the coupling means, more particularly coupling parts, of the second pair of edges of the second floor panels are compatible with each other, such that, when a first floor panel and a second floor panel are coupled to each other, via edges of their first pair of edges, a horizontal as well as a vertical locking is maintained, as well as such that, when a first floor panel and a second floor panel are coupled to each other, via edges of their second pair of edges, also a horizontal as well as a vertical locking is maintained.
  • first floor panels and coupling parts of the herein above-defined “second floor panels” can be realized compatible, at least in certain respects, with the advantage that first floor panels can be coupled to previously installed second floor panels and/or second floor panels can be coupled to previously installed first floor panels and/or first and second floor panels can be used in a mixed manner in one and the same floor covering.
  • This offers the advantage that a manufacturer of floor panels can switch from one coupling system to another without problems, by which a freedom is created by which he has the possibility to perform such switching in function of technical and/or economical causes.
  • the manufacturer in respect to decorative appearance or surface of the panels, can proceed with the same range of products, while the coupling parts are altered. Due to the compatibility of the floor panels the commercialization simply can continue without the installing person having to take care that the first and second floor panels are used in one and the same floor covering, as this, thanks to the invention, does not pose a problem.
  • the invention in general relates to floor panels for forming a floor covering, and more particularly for forming a decorative floor covering, as well as to a method of installing said floor covering. More particularly, this also relates to floor panels which can be installed floatingly. According to the invention, this can relate to floor panels of any material or of any composition.
  • Some practical examples are laminate floor panels; floor panels with a wood-based substrate, such as an MDF of HDF board; "engineered wood” panels; synthetic material-based floor panels, such as bendable or rigid so-called LVT; floor panels with a substrate of another material than wood or synthetic material; or floor panels which are composed of a plurality of material layers, such as floor panels with a substrate, whether or not synthetic material-based and whether or not foamed or provided with fillers, on which a decorative top layer of another material is provided, for example of wood, stone, synthetic material, such as a vinyl layer.
  • the floor panels can be realized in any appropriate thicknesses. In practice, these thicknesses may vary between 2 and 15 mm.
  • FIGs 1 and 2 is represented how "first" floor panels 1A can be installed via the fold-down technique.
  • This fold-down technique is known as such and also is valid for interconnecting "second" floor panels, as well as for compatibly installing and mutually connecting of, according to the invention, mixed use of first and second floor panels 1A and 1B.
  • Figure 2 moreover clearly illustrates by means of the indicated turning movement R and downward movement M how is proceeded with such fold-down technique.
  • composition and manner of mutually coupling of the first floor panels 1A are represented in Figures 3 to 6 .
  • the first floor panels 1A show at least the following characteristics:
  • composition and the manner of mutual coupling of the second floor panels 1B are represented in figures 7 to 10 .
  • the second floor panels 1B show at least the following characteristics:
  • the invention is characterized in that the coupling means, more particularly coupling parts 6A-7A, of the first pair of edges 2A-3A of the first floor panels 1A and the coupling means, more particularly coupling parts 6B-7B, of the first pair of edges 2B-3B of the second floor panels 1B are compatible with each other, as well as the coupling means, more particularly coupling parts 8A-9A, of the second pair of edges 4A-5A of the first floor panels 1A and the coupling means, more particularly coupling parts 8B-9B, of the second pair of edges 4B-5B of the second floor panels 1B are compatible with each other, such that, when a first floor panel 1A and a second floor panel 1B are coupled to each other, via edges of their first pair of edges, a horizontal as well as a vertical locking is maintained, as well as such that, when a first floor panel 1A and a second floor panel 1B are coupled to each other, via edges of their second pair of edges, also
  • the coupling parts at the first pair of edges 2A-3A of the first floor panel 1A and the first pair of edges 2B-3B of the second floor panel 2B are compatible in that they are realized identically. It is noted that here, also, compatible coupling parts can be used, which in respect to design differ from each other, in other words that the coupling parts of the "first" floor panels and the "second" floor panels have a shape differing from each other, however, still fit into each other in a locking manner.
  • the coupling parts in Figures 4 and 8 are formed of so-called "Uniclic" profiles, known, amongst others, from WO 97/47834 .
  • any coupling profile can be applied, so, for example, also the so-called 2G profile developed by the Välinge company, as well as a profile which in the meantime is widely known in the sector, of which the underside of the tongue is convex, for example approximately semicircular, whereas the recess in the longer lower lip then is concave.
  • This last-mentioned profile form, as well as other applicable profile forms, are known from US 4.426.820 .
  • Figures 11 and 12 illustrate how the hook-shaped parts of the second pairs of edges of the first floor panel 1A and the second floor panel 1B are compatible with each other and thus fit into each other and thereby maintain offering a mechanical locking in horizontal direction as well as in vertical direction.
  • a "first” and a “second” floor panel does not necessarily have to be the same, in other words, has to be realized with the same strength as the locking effect that is obtained between two of the same floor panels.
  • Figure 11 shows how the upper hook-shaped part 11A of a "first" floor panel 1A fits into the lower hook-shaped part 10B of a "second" floor panel 1B
  • Figure 12 shows how the upper hook-shaped part 11B of the "second" floor panel 1B fits into the lower hook-shaped part 10A of the "first” floor panel 1A.
  • a clamping represented in solid line, or a space, represented in dashed line, can be provided.
  • the vertical locking is obtained by the cooperation of the locking parts 18A and 20B, as well as by the cooperation of the locking part 19A with a locking part 21B provided at the floor panel 1B.
  • the vertical locking is obtained by the cooperation of the locking parts 20A and 18B.
  • the locking part 21A then is inactive.
  • Figure 13 represents first floor panels 1A which are coupled at the respective edges.
  • the floor panel 1A comprises a part 36A, which, when coupled with floor panel 1B, such as represented in figure 14 , at least partially cooperates with locking part 30B in order to provide for an extra locking.
  • This thus means that in the coupled condition of figure 14 a vertical locking as a result of the cooperating locking parts 20A and 18B is present, as well as a result of the cooperation of the locking parts 36A and 30B.
  • first and second floor panels in mutually coupled condition preferably at their upper surface adjoin each other in a normal manner, whether or not with the intermediary of a chamfer or the like.
  • the floor panels 1A and 1B can be realized such that at the location of C1A and C1B no vertical lockings exist and for example only vertical contacts exist.
  • the coupling parts 6A and 7A preferably consist of a horizontally locking tongue and groove connection.
  • the tongue 37A and the groove 38A provide for the vertical locking, while locking parts 39A and 40A provided thereon provide for that a horizontal locking is obtained, such in that the locking part 39A in the coupled condition engages behind the locking part 40A and in this manner, seen in cross-section, prevents or at least counteracts the shifting apart of the tongue 37A and the groove 38A.
  • the coupling parts 6B and 7B preferably consist of a horizontally locking tongue and groove connection.
  • the tongue 37B and the groove 38B provide for the vertical locking, while locking parts 39B and 40B provided thereon provide for that a horizontal locking is obtained, such in that the locking part 39B in the coupled condition engages behind the locking part 40B and in this manner, seen in cross-section, prevents or at least counteracts the shifting apart of the tongue 37B and the groove 38B.
  • the invention is intended in particular for being employed with oblong floor panels 1A-1B, thus, floor panels with long sides and short sides, wherein the first pair of opposite edges then preferably forms the long sides and the second pair of opposite edges then forms the short sides.
  • the floor panels are configured such that they can be installed by means of the fold-down principle.
  • Figures 15 to 18 represent another embodiment of two floor panels 1A and 1B, which, at their first pair of opposite edges, comprise compatible coupling parts 6A-7A and 6B-7B, which coupling parts now differ from each other for the floor panels 1A and 1B in respect to shape, however, in accordance with the present invention in fact are compatibly coupleable.
  • figure 15 shows the first pair of opposite edges 2A-3A of the first floor panel 1A, in a cross-section similar to that of figure 4 .
  • Figure 16 shows the first pair of edges 2B-3B of the second floor panel 1B, in a cross-section similar to that of figure 8 .
  • Figure 17 represents that the coupling part 6A is coupleable to the coupling part 7B and figure 18 represents that the coupling part 6B is coupleable to the coupling part 7A.
  • the floor panels 1A and 1B of the embodiment represented in figures 15 to 18 preferably are also oblong.
  • the first pair of edges of each of the floor panels in this case as well preferably is situated at the long sides thereof.
  • compatible coupling parts are provided as well, for example, coupling parts analogous to those depicted in figures 5 and 9 .
  • compatible coupling means or “compatible coupling parts” has to be understood that such coupling parts or coupling means allow coupling the coupling parts to each other in such a manner that a vertical as well as a horizontal locking is obtained.
  • this does not exclude that such vertical or horizontal locking can or cannot be performed with a play or pretension, in other words, press-fit, in vertical and/or horizontal direction.
  • first floor panels are mutually coupled, or second floor panels are mutually coupled, there is no play or indeed there is play, whereas, when a first and a second floor panel are coupled to each other, vice versa there is play indeed or there is no play in vertical and/or horizontal direction.
  • a downward movement M normally a movement is meant wherein, seen in a cross section on the respective edges, thus, according to cross-sections such as, for example, represented in figures 5 , 9 , 11 and 12 , the projections of the upper sides in these cross-sectional planes remain parallel or substantially parallel to each other during the downward movement.
  • the downward movement does not have to be perfectly vertical, as during the downward snapping-in a slight lateral shifting may occur when the respective coupling parts fit into each other in a self-searching manner.
  • coupling parts which, as aforementioned, are configured such that the floor panels, by means of these coupling means, can be coupled to each other by means of a turning movement, can be realized in various forms.
  • a tongue and groove of the type wherein the groove 38A, 38B, respectively, is bordered by an upper lip and a lower lip, wherein the lower lip laterally reaches farther than the upper lip, and wherein the respective locking part 40A-40B is situated at least partially and preferably entirely in that portion of the lower lip which protrudes beyond the end of the upper lip.
  • the compatible vertical locking preferably is obtained at least via locking parts which belong to the aforementioned first contact zones C1A and C1B, in the example the locking parts 18A with 20B and/or 18B with 20A.
